PROBLEM TO BE SOLVED: To provide a new polymerizable resin composition having sufficiently high storage stability even after the addition of a cure accelerator to a radical- polymerizable resin and quickly curable after starting the curing. SOLUTION: The polymerizable resin composition contains (A) a radical- polymerizable resin and (B) a 2-oxocarboxylic acid. More concretely, the 2- oxocarboxylic acid B is at least one kind of compound expressed by general formula (1) (Y1 and Y2 are each independently H, Cl, Br, F or a 1-10C straight or branched-chain alkyl; and X is lithium, sodium, potassium or ammonium).
